SDC4 and liver cancer: We analyzed SDC4, RAB27A, ARG1, and AXIN2 basal mRNA expression in five different liver cancer cell lines, each with a different CTNNB1 mutational status, and identified positive correlations between SDC4 and RAB27A with ARG1 (ß-catenin-negative target) and negative correlations between SDC4 and RAB27A with AXIN2 (ß-catenin-positive target) (Figure 3—figure supplement 2).
